With secondhand gene, 'freaky mouse' defeats common poison
Over millennia, mice have thrived despite humanity's efforts to keep them at bay. A Rice University scientist argues some mice have found two ways to achieve a single goal -- resistance to common poison.
New nanodevice defeats drug resistance
Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking ...
Study suggests why, in some species, mere presence of males shortens females' lifespan
Researchers at the Stanford University School of Medicine have discovered that males of the laboratory roundworm secrete signaling molecules that significantly shorten the lifespan of the opposite sex.
Antibiotic resistant bacteria proliferate in agricultural soils
Infectious diseases kill roughly 13 million people worldwide, annually, a toll that continues to rise, aided and abetted by resistance genes. Now a study, published in the March Antimicrobial Agents and Chemotherapy finds ...
Please Don't Eat the Daisies: The macroevolution of alternate plant defense strategies
Scientists help deliver genetic one-two blow to deadly wheat disease
(Phys.org) —A new gene that will equip wheat plants to resist the deadly stem rust disease has been discovered by an international team that includes plant scientists at the University of California, Davis.
Study shows evolutionary adaptations can be reversed, but rarely
(PhysOrg.com) -- Ever since Charles Darwin proposed his theory of evolution in 1859, scientists have wondered whether evolutionary adaptations can be reversed.
Researchers crack the genetic secret of mosquito resistance to DDT and ITNs
Researchers from LSTM have found that a single genetic mutation causes resistance to DDT and pyrethroids (an insecticide class used in mosquito nets). With the continuing rise of resistance the research, published in the ...
Aging gene found to govern lifespan, immunity and resilience
(PhysOrg.com) -- Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) at the University of Birmingham have discovered that a gene called DAF-16 is strongly involved in determining ...
Mutation breaks HIV's resistance to drugs
The human immunodeficiency virus (HIV) can contain dozens of different mutations, called polymorphisms. In a recent study an international team of researchers, including MU scientists, found that one of those mutations, called ...
Bacteria evolve resistance more quickly when stronger antibiotics are used
New scientific research published today in the journal PLoS Biology shows that bacteria can evolve resistance more quickly when stronger antibiotics are used.
Horizontal gene transfer in microbes much more frequent than previoulsy thought
Obese father rats have unhealthy daughters
'Nanobubbles' plus chemotherapy equals single-cell cancer targeting
Using light-harvesting nanoparticles to convert laser energy into "plasmonic nanobubbles," researchers at Rice University, the University of Texas MD Anderson Cancer Center and Baylor College of Medicine (BCM) ...
